Original application filed November 26, 1897, Serial Ne. 659,888. Divided and this application filed August 2S, 1909. Seri-si No. 514,999..

'7h (1.77 whom it may concern.'

zen ot' the lf'nited States, residing at Lowell, county ot llliddlesex, and Statev ot Massa ehusetts. have invented an Improvement in Yt-inding lilechanism, of which the follow ing description. in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts. l

This invention has for its object to provide a novel winding' mechanism especiall)v adapted for braiding machines. although capable of use in other relations.

The intention illustrated and claimed in this application has been divided out ot my' co-pending application Se. No. 659.885, tiled Xovemher QG. 199i, and this application is, therefore, a division of said former application.

ln the drawings, Figure l is a side. view oi a braiding machine showing in v improved winding mechanism as applied thereto; Fig. .2 is an end View of the winding mechanism: Fig. il is a section on the line a-.r, Fig; l: Fig. 4 is a detail view sou'iewhat enlarged showing the end of the winding finger.

Although l have shown in v improved Y used in connection with a. h `aiding machine, I do not wish to he limited to such use. l

l have shown in the drawings at 5l a braiding machine which may have anwv suitable 0r usual character, but which is illustrated` as having the saine characteristics as that embodied in the braiding machine shown in my above-mentioned (1o-pending applicib tion. T his braiding machine is one designed to braid cords, and as the braided cord c is .delivered from the braiding machine, it passes to the guide roll K2 and from thence passes to a takeup device K', and thence over a direction pulley K3, and thence to a tension regulator K4. and thence to another direction pulley K7, from whence it passes to the winding mechanism.

The parts above referred to are or ma)T be all as shown in my said cti-pending applica tion and form no part of my present in- Yention.

The cord e is wound on a drum or reel P which is supported in suitable stands This reel is frictionally rotated in some suit,- able way, and as herein illustrated, this is f accomplished h v an endless cable 77 which lle it known that. l, Patin Bif'rnnu, a cltii passes around a sheave p at' the end ot the reel and thence passes over a douhle-grooved' j pulley p2 tast on the shaft 7.1s ot the/tension regulator, a spring-actuated puller block p3 being supported in a loop of the endless cable for the purpose ot umintaining an even tension. 'lhispnlley block pi is connected to one end ot a spring s. the other ly end of which is connected at p* to some fixed object. The shaft. 7..-.8 is positively vdriven from a shaft. 7.',3 hv means of the worm gear lf and worm 7a", all as shown in *2 said eo-pending application. The spring s keeps vthe cord or cable 72 under sutlicient tension to drlve the reel h v the frictional engagement ot the cord with the pulle)T or sheave 7). The braided cord is delivered from the braiding machine at a constant rate ot speed and as the size of the rcel increases there will be more or less slippage between the cable 72 and the sheave 7i.

The cord or rope isweund snugl;Y upon the reel or drum P by or through the action of an arm ps having at its end a suitable finger p. preterablielongated in shape and pivotally connected with the said arm at 7)?. which finger acts against the last-laid coil of the cord c. The arm 71S is provided at its end with a groove 717 through which the cord passes and which acts to guide the cord. Said arm is shown in Fig. l as moving toward the right, but after the completion of the layer then being made and the arrival of the arm 79s at the right. hand inner side of the head of the said drum or rcel, the arm yf* will be lifted b v the coil of yarn being laid and the first coil of a new layer will he laid, and the finger p will drop oft from it, and, acting on the left hand side of said firsty coil, will afterward commence to act on the right hand side of said linger p, and will cause it and the arm p8 to be moved to the left hand end of the drum or reel.

The hub of the arm ps is mounted loosely on a shaft p9, which is rotated by suitable means, as a sprocket chain 721, geared therewith, and deriving its motion from the shaft. L of the take-up and tension device. This shaft 7J is also driven from the shaft 7c3 by means of a worm gear 7:5 fast ou the shaft which meshes with the worm gear 7e". In my experiments I have found that rotating the shaft p is a very important operation because the arm ps could not. be slid i practically from one end to the other of a stationary shaft merely by the pressure on the arm of the cord as it is being: wound "ith the device as herein illustrated, however, this winding arm p8 will move freely and easily lmckward and forward and the cord will be wound eve dy and uniformly on the reel.

The finger 7; is pivoted in order that it may acconmiodate itself to the increasing size of the' l'eel as the cord builds up. lt will be noted that the finger moves ahead of the cord being laid. In other words. that the last turn of the cord presses against the side of the finger and thus pushes the arm forward. The force necessaryY to push tbe arm is sufiieient to hold the last turn of the cord tightly against the preceding` turn, and the position of the =frroovey p7 is such that thefcord is laid closely against the preceding turn as the drum is wound. vhen the finger reaches the end of the reel. the cord bein;r wound crowds it up and then said finger automatically drops down over the cord as the first4 turn is made for the return coil and thereafter the arm 728 will be moved in a reverse direction until the end of the reel is reached.

)L winding mechanism as above described has especial advantage when used in connection with a braiding machine, but it is also capable of being used in connection with other machines.

Havingr fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a winding mechanism, the combination with a drum or reel, of means to rotate it, a smooth shaft, an arm loosely mounted thereon, a winding linger carried by and movable on said arm and adapted to rest on the reel at one side of the cord as it is winding, and means to rotate said shaft.

2. In a winding mechanism, the combination with a drum or reel, of means to rotate l 1t, a. smooth shaft, an arm loosely mounted thereon, a windingr finger pivoted to the arm and adapted to restv loosely on the reel at one side of the cord as it is winding', and means to rotate said shaft.

3. In a winding` mechanism, the combination with a drum or reel, of means to rotate it, an arm fgee to be slid parallel to the axis of said drum and provided with a windingr finger to act on the side of the cord adjacent the point where it is bein,"l delivered on said drum, the layingof the cord in successive coils acting' on said finger to cause it and its arm to travel in the direction of the length of the drum, said finger yieldingto the last coil of the wound layer and assumingF a position in front of the first coil of the next layer.

4. In a winding mechanism. the combination with aV drum or reel havingY a sheaf connected therewith, of a cable passingY over said sheaf and havingfrictional engagement. with the sheaf for rotating the drum', a

spring for maintaining the cable under-a uniform tension, a smooth shaft. an arm loosely mounted thereon, a windingr linger carried by and movable on said arm and adapted to rest on the reel at one side of the cord as it is winding, and means to rotate said shaft.

In testimony whereof, have signed my name to this specification, in the presence of two subscribing witnesses. f
